Thank you for your replies.
Tonight I tried imaging with Maxim DL 5 on Win7 with everything directly connected to the main Win7 computer. Every device is connected and recognized by Maxim DL 5 alright including the OK3 focuser but now the focuser does not work! When I captured the above images with Stellarmate I used the same Win7 computer for focusing and the OK3 focusing software worked! Now I am in a Catch 22 situation. Since the focuser does not work, I cannot confirm with Ekos if the defects are caused by icing or from other causes. I have no idea how I can get the OK3 focuser working again on the Win 7 computer. Does anyone have a copy of the OK3 focuser controlling software? The previous owner misplaced the original software CD packages and so there is no way to reinstall the software. I wonder if there is an archive of old astrophotography software.
Ekos works fine with the Apogee camera and the FLI filter wheel except for the OK 3 focuser. ASA10N is a laser sharp fine instrument. I would love to capture images with is fine instrument. ASA stopped making small aperture telescopes for amateurs and seems to be uncooperative regarding inquiries about their old telescopes.
